Agencies like the NSA are currently able to eavesdrop on anyone with few restrictions only - though other messages are spread by the NSA.
Theoretically cryptography can make that difficult. Hence those agencies speak up for actions like introducing trapdoors to make it possible to get access to everybody's data.
See the U.S. discussion about the Clipper Chip some years ago:
While encryption offers us privacy for the transmission of data, we do not only wish to have it but also need it if we want to transport data which shall not be seen by anyone else but the recipient of our message. Given this, the governments and governmental institutions/organizations fear to lose control. Strict laws are the consequence. The often repeated rumor that the Internet was a sphere of illegality has been proven wrong. Some parts are controlled by law very clearly. One of them is cryptography. Prohibition of cryptography or at least its restriction are considered an appropriate tool against criminality. Or one should say: had been considered that. In the meantime also governmental institutions have to admit that those restrictions most of all work against the population instead against illegal actors. Therefore laws have been changed in many states during the last five years. Even the USA, the Master of cryptography-restriction, liberated its laws in December 1999 to be more open-minded now.

Gutenberg's printing press was an innovative aggregation of inventions known for centuries before Gutenberg: the olive oil press, oil-based ink, block-print technology, and movable types allowed the mass production of the movable type used to reproduce a page of text and enormously increased the production rate. During the Middle Ages it took monks at least a year to make a handwritten copy of a book. Gutenberg could print about 300 sheets per day. Because parchment was too costly for mass production - for the production of one copy of a medieval book often a whole flock of sheep was used - it was substituted by cheap paper made from recycled clothing of the massive number of deads caused by the Great Plague.
Within forty-five years, in 1500, ten million copies were available for a few hundred thousand literate people. Because individuals could examine a range of opinions now, the printed Bible - especially after having been translated into German by Martin Luther - and increasing literacy added to the subversion of clerical authorities. The interest in books grew with the rise of vernacular, non-Latin literary texts, beginning with Dante's Divine Comedy, the first literary text written in Italian.
Among others the improvement of the distribution and production of books as well as increased literacy made the development of print mass media possible.
Michael Giesecke (Sinnenwandel Sprachwandel Kulturwandel. Studien zur Vorgeschichte der Informationsgesellschaft, Frankfurt am Main: Suhrkamp, 1992) has shown that due to a division of labor among authors, printers and typesetters Gutenberg's invention increasingly led to a standardization of - written and unwritten - language in form of orthography, grammar and signs. To communicate one's ideas became linked to the use of a code, and reading became a kind of rite of passage, an important step towards independency in a human's life.
With the growing linkage of knowledge to reading and learning, the history of knowledge becomes the history of reading, of reading dependent on chance and circumstance.

Although the traditional media companies first steps into the digital sphere were fairly clumsy, they have quickly learned from their mistakes and continued to enlarge their Internet presence.
During the last years many of the smaller players in the field of digital media have been driven out of competition by the huge media conglomerates. This mainly is a result of the advantages that the commercial media giants have over their less powerful counterparts:
- As engagement in online activities mostly does not lead to quick profits, investors must be able to take losses, which only powerful companies are able to.
- Traditional media outlets usually have huge stocks of digital programming, which they can easily plug into the Internet at little extra cost.
- To generate audience, the big media conglomerates constantly promote their Websites and other digital media products on their traditional media holdings.
- As possessors of the hottest "brands" commercial media companies often get premier locations from browser software makers, Internet service providers, search engines and portals.
- Having the financial resources at their disposition the big media firms are aggressive investors in start-up Internet media companies.
Commercial media companies have close and long ties to advertisers, which enables them to seize most of these revenues.

Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to
Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and

Universally accepted system of writing used by and for blind persons and consisting of a code of 63 characters, each made up of one to six raised dots arranged in a six-position matrix or cell. These Braille characters are embossed in lines on paper and read by passing the fingers lightly over the manuscript. Louis Braille, who was blinded at the age of three, invented the system in 1824 while a student at the Institution Nationale des Jeunes Aveugles (National Institute for Blind Children), Paris.
Galileo Galilee (1564-1642), the Italian Mathematician and Physicist is called the father of Enlightenment. He proofed the laws of the free fall, improved the technique for the telescope and so on. Galilee is still famous for his fights against the Catholic Church. He published his writings in Italian instead of writing in Latin. Like this, everybody could understand him, which made him popular. As he did not stop talking about the world as a ball (the Heliocentric World System) instead of a disk, the Inquisition put him on trial twice and forbid him to go on working on his experiments.

Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, the punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology for processing statistical data retrieved from the US census in 1890, thus speeding up data analysis from eight to three years. His application of Jacquard's invention was also used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with
Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone applied them as a medium for the preparation, storage, and transmission of data for the first time. By their means, telegraph messages could be prepared off-line, sent ten times quicker (up to 400 words per minute), and stored. Later similar paper tapes were used for programming computers.
This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.
